Stop in for a cup of coffee

Well, I was supposed to have company this weekend. Took tonight off cause my son was going to be here. Well, his girlfriend has to work because her coworker is out sick. So, now they may show up next weekend and I don't know if I will be able to take off. :BangHead:
I did text my boss and offered to work tonight. That would make it a whole lot easier to take next Saturday. Haven't got a response yet.
